Gary Taubes and the Cause of Obesity

Gary Taubes has written two books explaining why people get fat and why a low-carb diet is the solution to preventing and treating obesity. He didn’t like what I had to say about his books on this blog back in 2011. I was not the only one to criticize. Another reviewer accused him of “abandon[ing] journalistic and scientific integrity in place of observational data, straw men and logical fallacy.” He says he agrees with Taubes’ premises but that his “arguments made me cringe,” and he goes into considerable detail to explain why. His analysis is worth reading.

Rather than engaging in the Comments section, Taubes complained to me in a somewhat offensive personal e-mail, saying I had failed to understand what he wrote. Recently he e-mailed me again, condescendingly suggesting that I might understand his arguments better if I read an article he wrote last year for the British Medical Journal. I read it, and confirmed that I had understood perfectly well the first time around and that it was Gary Taubes who didn’t understand my criticisms. I pointed out some omissions and inconsistencies, but my major criticisms boiled down to two:

  1. The clinical evidence isn’t yet sufficient to convincingly prove his thesis. (He himself admitted this.)
  2. He strongly recommended that everyone adopt a low-carb diet, essentially insisting that we act on insufficient evidence. And this was after he had devoted whole chapters of his books to demonizing the low-fat diet advocates for doing exactly that: acting on insufficient evidence.

Why We Get Fat

Journalist Gary Taubes created a stir in 2007 with his impressive but daunting 640-page tome Good Calories, Bad Calories.  Now he has written a shorter, more accessible book Why We Get Fat: And What to Do About It to take his message to a wider audience. His basic thesis is that:

  • The calories-in/calories-out model is wrong.
  • Carbohydrates are the cause of obesity and are also important causes of heart disease, type 2 diabetes, cancer, Alzheimer’s, and most of the so-called diseases of civilization.
  • A low-fat diet is not healthy.
  • A low-carb diet is essential both for weight loss and for health.
  • Dieters can satisfy their hunger pangs and eat as much as they want and still lose weight as long as they restrict carbohydrates.

He supports his thesis with data from the scientific literature and with persuasive theoretical arguments about insulin, blood sugar levels, glycemic index, insulin resistance, fat storage, inflammation, the metabolic syndrome, and other details of metabolism. Many readers will come away convinced that all we need to do to eliminate obesity, heart disease and many other diseases is to get people to limit carbohydrates in their diet. I’m not convinced, because I can see some flaws in his reasoning. (more…)
